简单常用方法接口_2

第三步，定义具体dao接口
package dao;

import bean.entity.Clothes;

public interface ClothesDao extends GenericDao<Clothes,Integer> {

}
第四步，实现dao
package imp;

import bean.entity.Clothes;
import dao.ClothesDao;

public class ClothesDaoImpl extends GenericHibernateDaoImpl<Clothes,Integer> implements ClothesDao{

}
第五步，定义业务层service接口
package zip;

import java.util.List;

import tool.PageBean;
import bean.entity.Clothes;

public interface ClothesService {

/**
* 增加衣服
* @param emp
* @return boolean
*/
public boolean addClothes(Clothes c);

/**
* 获得所有厂服订制详细信息
* @return List
*/
public List queryClothes();

/**
* 根据编号获得订制的厂服
* @param cid
* @return
*/
public Clothes getClothes(String htl);

/**
* 更新厂服订制
* @param c
* @return
*/
public void updateClothes(Clothes c);

/**
* 删除订制
* @param cid
*/
public void deleteClothes(Clothes c);

/**
* 分页查询
*
* @param currentPage
*            当前第几页
* @param pageSize
*            每页大小
* @return 封闭了分页信息(包括记录集list)的Bean
*/
public PageBean queryForPage(int pageSize, int currentPage);
}
第六步，实现业务层
package imp;

import java.util.List;

import tool.PageBean;
import zip.ClothesService;
import bean.entity.Clothes;
import dao.ClothesDao;

public class ClothesServiceImpl implements ClothesService{

private ClothesDao clothesDao;

public ClothesDao getClothesDao() {
return clothesDao;
}
public void setClothesDao(ClothesDao clothesDao) {
this.clothesDao = clothesDao;
}

public boolean addClothes(Clothes c) {
// TODO Auto-generated method stub
return clothesDao.add(c);
}

public List queryClothes() {
// TODO Auto-generated method stub
return null;//dao.queryClothes();
}

public Clothes getClothes(String hql) {
// TODO Auto-generated method stub
return clothesDao.findById(hql);
}

public void updateClothes(Clothes c) {
// TODO Auto-generated method stub
//dao.updateClothes(c);
clothesDao.update(c);
}

public void deleteClothes(Clothes c) {
// TODO Auto-generated method stub
clothesDao.delete(c);
}

public PageBean queryForPage(int pageSize, int currentPage) {
// TODO Auto-generated method stub
//查询语句
final String hql = "select c.cid,e.eid,e.ename,e.esex,e.edept,c.longSleeve,c.shortSleeve,c.csize,c.cremark " +
"from Clothes as c inner join c.employee as e where e.eid=c.employee.eid";
//int allRow = dao.getAllRowCount(hql);//总记录数
int allRow = clothesDao.getTotal(hql);//总记录数
int totalPage = PageBean.countTotalPage(pageSize, allRow);//总页数
final int offset = PageBean.countOffset(pageSize, currentPage);//当前页开始记录
final int length = pageSize;//每页记录数
final int pageNo = PageBean.countCurrentPage(currentPage);
//List list = dao.queryForPage(hql, offset, length);//"一页"的记录
List list = clothesDao.findList(hql,offset, length);//"一页"的记录

//把分页信息保存到Bean中
PageBean pageBean = new PageBean();
pageBean.setPageSize(pageSize);
pageBean.setCurrentPage(pageNo);
pageBean.setAllRow(allRow);pageBean.setTotalPage(totalPage);
pageBean.setList(list);
pageBean.init();
return pageBean;
}
}
第七步，控制层实现action
public ActionForward deleteClothes(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {

String cid = request.getParameter("cid");
System.out.println(cid + "*******cid");
Clothes c = new Clothes();
c.setCid(Integer.valueOf(cid));
clothesService.deleteClothes(c);

//删除成功与否回到结果页面
return this.queryClothes(mapping, form, request, response);
}
